WINDOW CONSTRUCTION 5 SheetsSheet 3 I k QQw' Inventor Patented Feb. 25, 1936 UNETEE STA'E'EI PATENT OFFICE 1 Claim.

This invention appertains to new and useful improvements in window constructions either of the wooden or metallic type.

The principal object of the present invention is to provide a window construction which while primarily intended to afford indirect ventilation, is at the same time a positive safeguard against unlawful entry from the outside.

Another important object of the invention is to provide means for actuating the sashes simultaneously through the use of a single operating member, wherein said member is provided with latch means for maintaining the sashes of the Window in any definite adjusted position.

These and various other important objects of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents an inside elevational View of the improved window.

Figure 2 represents a side elevational view of the window showing the counter balancing weight for the sashes.

Figure 3 represents a side elevational view looking at the opposite side of the window from that shown in Figure 2.

Figure l represents a vertical sectional view taken substantially on line l-- -i of Figure 1 showing the sashes and ventilating panels in closed position.

Figure 5 is a vertical sectional view on substantially the same plane of Figure l as Figure 4, and showing the sashes in closed. position but the ventilator panels in open position.

Figure 6 represents a vertical sectional view taken substan Laliy on the same plane of Figure 1 as Figure 4, but showing the sashes in open position.

Figure '7 is an enlarged fragmentary sectional view taken substantially on line 'i? of Figure 1.

Figure 8 is an enlarged fragmentary detailed sectional view taken on line 88 of Figure 1.

Figure 9 is a fragmentary elevational view of one of the ventilators showing one of its lugs.

Figure 10 represents a sectional View on line Y l0-l6 of Figure 4.

Figure 11 represents one of the sash and chain connectors.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numerals 56 represent a vertical side of the window frame, While numeral '2 is the horizontal top member. The sill 8 supports the lower end of the side members 5-6 of the frame.

Secured to the inner side of the side wall 5 are the strip members 9 one on each side wall 56 to cover the upper ends of these strips 9 being connected by the horizontal strip l0'secured to the bottom side of the horizontal portion 7 of the window frame.

Secured to each of the strips 9 is a pair of substantially transversely disposed ribs l l--l2 for the upper and lower sashes l3l4 respectively. These ribs |l-I2 are each on an are having its diameter at the hinge I5 of the corresponding ventilator panel or pane ll or l8.

It can be seen that in the construction of the sash, each sash is made up of a substantially square-shaped frame 8 provided with an intermediate transversely disposed rail 1) which is rabbeted as at c to receive the edge portion of the corresponding Ventilator pane l8 which pane is swung only in an inward direction as shown in Figure 5. Each pane is provided with a lug l9 at each end thereof which projects laterally to deline the shoulder 29 for riding engagement, in the instance of the upper ventilating pane l8, against the top of the upper rib ll, while in the instance of the lower pane ll, against the bottom of the rib I2. In this manner when the ventilator I8 is open its lugs l9 will prevent the sash from being moved downwardly, while in the instance of the lower pane ll when open, this lug will prevent the lower sash I4 from being raised.

In the wall are the openings 2| in which pulleys 22 are mounted and over these pulleys are disposed the elongated chain 23. This chain at its end connects one to each of the sashes I3-l4, while on the outside of the Wall 5 and in the weight box carried by the side flanges 24 the chain is disposed under the pulley 25 which carries a weight 26. Thus the sashes are counterbalanced.

It can be seen in Figure 8 that each of the transverse intermediate members b of the sashes is provided with a spring projected vertical latch member 21 having a control knob 28, this latch or bolt being engaged into the socket 29 in the upper edge of the frame of the corresponding ventilator ll-l8.

The vertical wall 6 of the window frame is provided with the vertical slots 30-3 I, for the lower and upper sashes respectively. The flanges 24-44 at this side wall 5 are provided with the cross member 32 which between itself and the wall 6 supports the shaft 33 on which the sprocket wheel 34 is mounted and over which the sprocket chain 35 is trained. In this sprocket chain and in each flight thereof is a turnbuckle device 36 whereby the chain can be adjusted to the proper tautness.

The lower portion of this endless chain is disposed over the lower sprocket 31 which is keyed to the horizontal shaft 38 along with the beveled gear 39, which beveled gear meshes with the beveled gear 46 on the shaft M which is disposed at right angles to the shaft 38 and journalled through the bearing structure 42.

Numeral 43 represents a tubular shaft disposed through the front flange 24 of the sidewall 6 and this tubular shaft 43 is provided with a hinge bracket 44 at its outer end and with a hinge 45 at its inner end, said head 45 at its inner end being provided with teeth 46 meshable with the teeth 41 on the plate 48 secured to the inside of the last mentioned flange 24. The aforementioned shaft 4! extends into the tubular shaft 43 as shown in Figure '7 and is splined thereto as at 49.

By referring to Figures 3 and 11 it can be seen that each of the sashes is provided with a connector consisting of the plate 50 which is secured to the edge portion of the sash and this plate is provided with an outstanding web 5 I These webs 5| are slidably disposed through the slots 3!l3l in the side wall 5 of the frame shown in Figure 3, and small bolts can be disposed through the openings 52 in the outer corners of the web 5! and passed through links of the sprocket chains and provided with nuts, in which manner the sprocket chain 35 is secured to the sashes so that when the bracket 44 is gripped and the shaft 43 forced inwardly to the position shown in Figure 7, disengaging the teeth 46 from the teeth 41, and

the shaft 434I then rotating, motion will be imparted to the chains 35 so that the upper sash will be lowered, and the lower sash raised uniformly, as is suggested in Figure 6.

A spring 53 on the shaft 4! is interposed between the bearing 42 and the head serves to return the head so that the teeth 464'l mesh to prevent any operation of the sashes at any point apart from the operation of thecrank 44. Thus the sashes are locked in any position to which they are adjusted.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials are resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having thus described my invention, what I claim as new is:

In a window construction a pair of vertical side members, upper and lower sliding sashes, transversely extending ribs on the side members, each of said sashes being provided with a vertically swingable ventilating panel, the panel of the upper sash being provided with laterally disposed lugs for engaging over the upper rib on each of the side members, the lugs on the lower panel being adapted to engage the lower ribs at their under side, and stop strips extending vertically at the ends of the ribs away from the sashes to stop the lugs.
